Keep the legacy regexp static properties backed by PrimitiveString values instead of eagerly copied Utf16Strings. lastMatch, leftContext, rightContext, and $1-$9 now materialize lazy Substrings from the original match input when accessed. Keep RegExp.input as a separate slot from the match source so manual writes do not rewrite the last match state. Add coverage for that behavior and for rope-backed UTF-16 inputs.
